Hair treatments and hair dyes in pregnancy

Is it safe to use hair dye during pregnancy? Should other hair treatments be avoided in the first trimester or later in pregnancy? Hair dyes and other hair treatments are used frequently and many women wish to continue treating their hair while they are pregnant.

However, many types of hair dyes contain dangerous chemicals, as do other hair treatments like straighteners and bleaches. These chemicals can be absorbed through the skin and enter the mother’s circulation. Once in the mother’s blood, the chemicals from hair dyes may cross the placenta and enter the bloodstream of your developing foetus.

While further research is needed to determine whether these chemicals harm developing babies, until they are proven to be safe, it’s best to err on the side of caution. If you’re pregnant, you’re probably wanting to know exactly what the risks are and how they occur, as well as what you should do to ensure you minimise the risks of using hair dye while you’re pregnant.
